How is the performance of this relay affected by environmental conditions?
It operates effectively in temperatures ranging from -20 to +60°C and can withstand storage temperatures from -25 to 65°C, ensuring reliability in various settings.
What types of connections are required for operation?
It requires connections to L1, L2, and L3 for three-phase 3-wire mode or L1, L2, L3, and N for the three-phase four-wire mode, emphasising the importance of correct wiring configuration.
Can the overvoltage and undervoltage settings be adjusted?
Yes, both the overvoltage and undervoltage thresholds can be set between -30% to +25% of the rated input voltage, enabling precise control based on specific application needs.
How can phase loss be accurately detected with this relay?
Phase loss detection is achieved through monitoring voltage drops in any phase, allowing for a quick response to mitigate potential equipment damage.
